未显示数据表中的添加行？

Question

I've a simple code, here I add a row to my a datatable which is in my dataset:

 DigiLocalDataSet dataset = new DigiLocalDataSet();

 DataRow newClientsRow = dataset.Tables["clients"].NewRow();

 newClientsRow ["clientnr"] = "123";
 newClientsRow ["name"] = "Pascal";
 newClientsRow ["city"] = "London";

 dataset.Tables["clients"].Rows.Add(newClientRow);

 clientsTableAdapter.Fill(dataset.clients);

 this.DataContext = dataset.clients.DefaultView;

But I don't see the inserted row in my datagrid, I see only the existing rows of the 'clients' table.

What's wrong?

Answer 1

Check if clientsAdapter.ClearBeforeFill is set to true . Set it to false or call Fill() on the Clients table before adding the new row.

Answer 2

Your call to TableAdapter.Fill is filling your 'clients' DataTable with data retrieved from your data source, so you're losing the record you manually added to the DataTable.

Answer 3

Have you tried this?

 newClientsRow.BeginEdit();
 newClientsRow ["clientnr"] = "123";
 newClientsRow ["name"] = "Pascal";
 newClientsRow ["city"] = "London";
 newClientsRow.EndEdit();

Answer 4

I don't know the command but you need to post this row.

Answer 5

Did you accept changes to the dataset before refilling? fill pulls data from the store.
